Pathlib-like API

Pathlib-like API#

Full API#

  • Path(*parts: PathLike): pathlib-like abstraction.

Resource API:

  • resource_path(module_name: str | ModuleType) -> Path: Resource path (read-only).

  • to_write_path(path: Path) -> Path: Convert read-only resource path into writable path.

Typing API:

  • PathLike: str or pathlib object (typing annotation): path: PathLike

  • PathLikeCls: str or pathlib object (at runtime): isinstance(p, PathLikeCls)

Additional methods#

In addition of the pathlib methods, epath.Path has the additional methods:

  • path.copy(dst, overwrite=True)

  • path.rmtree()

  • path.format(*args, **kwargs): Apply str.format on the underlying path str

There are some discussions about adding those methods nativelly in pathlib.

FLAGS#

absl.flags support is provided to define FLAGS parsed as epath.Path:

from absl import app
from etils import epath

_PATH = epath.DEFINE_path('path', None, 'Path to input file.')


def main(_):
  content = _PATH.value.read_text()

if __name__ == "__main__":
  app.run(main)
Contents
